Is My iPhone Screen Original? How to Check a Replaced Screen

Short answer

Your iPhone keeps its own repair record, so start there, not with a flashlight. Apple says the Parts and Service History section appears on iPhones that have been repaired, on iOS 15.2 and later. If you see it and Display is listed, the screen you are looking at is not the one that left the factory, even if the label says Genuine.

That is the point most guides blur. “Genuine” and “original” are different things. Genuine means an Apple part. Original means the panel the phone was built with. A screen Apple replaced for you is genuine but not original, and for most people that is completely fine.

If your iPhone is too old to show a Display line, or the result looks odd, the checks further down will give you clues. Clues are all they are. Then run our screen test and touch test, because how the screen works matters more than where it came from.

Step 1: Check Parts and Service History

1. Update the iPhone if you can. The section needs iOS 15.2 or later.
2. Open Settings, tap General, then tap About.
3. Scroll down and look for Parts and Service History. Apple says it shows up if the iPhone has been repaired.
4. Tap it, if it is there, and read the line next to Display.

Apple says display history is available on iPhone 11 and later, except iPhone SE (2nd and 3rd generation). On foldable models, Apple’s page notes that Display can mean the inner or the outer screen. If a part has been serviced more than once, only the most recent service appears, so this is not a full history.

On iOS 15.1 or earlier, you won’t get this list. A non-genuine screen shows an “Important Display Message” instead.

What each label means

• Genuine: the repair used genuine Apple parts and processes. The screen is an Apple part, but it has been replaced.
• Used: the part is genuine but was already used in another iPhone. That is allowed and can be a fair repair, but a seller shouldn’t describe it as a new or original screen.
• Unknown: this does not always mean a fake. Apple says it can mean the screen isn’t a genuine part, isn’t working as expected, hasn’t been verified and linked to the iPhone after the repair, or has been modified or can’t be verified.
• Finish Repair: calibration wasn’t completed. Apple says the phone can still be used, but the part may not perform as well, and Face ID or Touch ID may be unavailable until the repair is finished.

Apple says the first notice about an Unknown part appears the first time you unlock the iPhone after the repair, and again five days later. If you bought the phone used, you may never have seen either one, so don’t treat the lack of a pop-up as a clean result. Always open the screen in Settings yourself.

Apple also says these messages don’t stop you from using the iPhone. An Unknown screen is not a lock, and the phone will not shut off because of it.

What it means if the section isn’t there

On iPhone 11 or later with a current iOS, no section means iOS has no repair to show you. That is the result you want on a phone sold as “all original”. Apple’s page doesn’t promise the reverse, though, so don’t read it as a guarantee that the phone has never been opened.

On iPhone XS, XS Max, XR and iPhone SE (2nd and 3rd generation), the history doesn’t cover the display, so a missing line tells you nothing. Use the next section.

Step 2: Look for physical and display clues

None of these prove anything alone. Two or three together are worth taking seriously.

• True Tone switch. Open Settings → Display & Brightness. On a model that came with True Tone, a missing switch can point to a replaced screen. Apple lists True Tone trouble among the problems a non-genuine display can cause, but the feature can also be missing because a repair wasn’t set up properly.
• Edges. Look along the seam between the glass and the frame. Uneven gaps, a raised edge, stray glue or dust under the glass suggest the phone has been opened.
• Colour and brightness. On a white page at full brightness, check for a yellow or blue tint or uneven patches. Apple names both, along with lower maximum brightness. Compare with another iPhone of the same model if you can, because judging tint alone is unreliable.
• The black screen test, with care. Many guides say a genuine screen is always pitch black in a dark room. That only applies to OLED models. Apple’s own spec page for iPhone 11 calls its screen LCD, and an LCD glows faintly on black from the factory. Check your model on Apple’s tech specs page first. A clearly glowing black screen on an OLED model is worth a closer look.

Some guides also suggest shining a flashlight at the glass and looking for grid lines. We couldn’t find any evidence that this works reliably, so we leave it out.

Step 3: Test how the screen works

Whether or not the screen is original, these are the faults you will live with. Apple’s list of problems from non-genuine displays is mostly about touch and light, which you can check in a few minutes.

1. Pixels and tint: run the screen test. It fills the display with solid colours. Our guide on dead and stuck pixels explains what you might find.
2. Touch: use the touch test and drag across the whole screen, especially the corners and edges. Apple says parts of the screen may not respond, or touches may land in the wrong place.
3. Phantom taps: run the ghost touch test and don’t touch the screen. See our ghost touch guide if anything registers.
4. Calls: make a call and hold the phone to your ear. Apple says a non-genuine screen may stay on during calls or pick up touches from your face. If it behaves oddly, read about screen problems during calls.
5. Auto-Brightness: move from a bright room to a dark one. The screen should adjust smoothly, not jump or stay dim.
6. Face ID or Touch ID: set it up or use it several times.

When to repair, replace or walk away

• Genuine label, everything works: nothing to do. Keep the repair receipt if you have one.
• Finish Repair showing: finish it. Apple’s Repair Assistant, added in iOS 18 for iPhone 12 and later, configures replacement parts, and MacRumors reports that this keeps True Tone and auto brightness available on a replacement display. If the option doesn’t appear or fails, go back to whoever did the repair.
• Unknown label, screen works well: you can keep using it. Apple says an Unknown part may lower trade-in value, so factor that in if you plan to trade in the phone. A shop’s repair warranty is the first thing to check if a fault appears later.
• Unknown label, touch or brightness faults: ask the repair shop to fix it if the repair is recent. Otherwise, get a quote from Apple or an Apple Authorized Service Provider for a genuine display, and compare it with what the phone is worth.
• Old phone with a failing screen: if the repair costs a big share of the phone’s value, replacing the phone is often the better deal, especially if the battery is worn too.

If you are buying a used iPhone

A replaced screen isn’t a deal-breaker. A hidden one is. Open Parts and Service History with the seller before you pay. If the listing says “original screen” and the phone shows Unknown or Used, either the seller doesn’t know or the listing is wrong. Either way, ask for a repair receipt and a lower price, or walk away.

The same check covers more than the screen, so use it for the battery too. Our used iPhone checklist covers the rest, and how to check if a phone is original or fake helps if you doubt the whole phone. Keep the used phone checklist open while you test.
